Gravel Ocean Sea Sand Transfer Pump

Gravel ocean sea sand transfer pumps are designed for continuously handling the most difficult higher abrasive slurries which contain too big solids to be pumps by a common slurry pump. The pump body(casing & impeller) are made of 27% high chrome alloy, the extra thick pump case let the pump anti-wear and need lowest maintenance cost.

Gravel Ocean Sea Sand Transfer Pump

Gravel Ocean Sea Sand Transfer Pump Structure

impeller：The impeller, either elastomer or high-chrome material, is the main rotating component which normally has vanes to impart the centrifugal force to the liquid.

Casing：Split outer casing halves of cast contain the wear liners and provide high operation pressure capabilities. The casing shape is generally of semi-volute or concentric, efficiency of which are less than that of the volute type.

Shaft and Bearing Assembly：A large diameter shaft with a short overhang minimizes deflection and vibration. Heavy-duty roller bearings are housed in a removable bearing cartridge.

Shaft sleeve：A hardened, heavy-duty corrosion-resistant sleeve with O-ring seals at both ends protects the shaft. A split fit allows the sleeve removed or installed quickly.

Shaft Seal：Expeller seal, Packing seal, Mechanical seal.
